Super Duplex Round Bar

Super Duplex Round Bar

Super Duplex Round Bar

Super duplex round bar is a metallic bar made out of super duplex grade stainless steel. There are different types of steel grades. It is a combination of ferritic and austenitic steel properties. there are standard duplex, lean duplex and super duplex stainless steels depending on their material composition. The Super Duplex Rod could be used in different applications ranging from aerospace to household and kitchen appliances.

All the super duplex bars are corrosion resistance and they are cost effective solutions for long term applications. Naman Pipe & Tubes is a manufacturer and supplier of different SDSS Bars & Billets. We produce the SDSS Flat Bar which is used in structural applications to make lattices and the A276 Hollow Bar which is used with lightweight applications. We also produce the SDSS Hex Bar which is used with some structural applications which need to be stronger such as in the construction industries. Apart from being applied in applications directly, the bars could also be used to produce accessories such as screws, bolts, nuts and nails of different shapes and sizes. Our Super Duplex Stainless Steel Round Bar Stock includes different sizes and finishes. Please contact us for various finishes, sizes and prices of round bars.

What is the forging process of super duplex round bars?

Forging is a process that applies localized forces to a piece of metal to reshape it into another shape. There could be different kinds of forgings applied to form any given material. There are drop forging, isothermal forging, multidirectional forging, induction forging, cold forging, press forging, upset forging, automatic hot forging and roll forging methods.

The super duplex material can be forged using compression forging, hot forging, open die forging, cold forging, impression die drop forging, closed die forging, press forging, upset forging and roll forging methods. Different methods would be used for different types of materials. Depending on the need, the nature of the round bar and the mechanical properties, the different methods would be selected.
